  • Patent number: 5349737
    Abstract: In a process for separating overlapping sheet metal panels, which are welded together by a series of spot-welds, the portion of each spot-weld in one of the panels is removed by drilling or milling after which pressure is applied by means of a tool, driven by a pneumatic hammer device, to the remaining portion of the spot-weld in the other panel forcing the other panel away from the one panel and separating of the panels without substantial damage to the panels. Alternatively, a hole saw may be used to separate the spot-weld from the one panel before pressure is applied to the spot-weld to separate the panels.

  • Patent number: 5048244
    Abstract: An underground shock-resistant structure comprises a vaulted roof having a ring configuration as viewed from above and a ring-shaped base member, such as a flat floor, joined to the inner and outer edges of the vaulted roof. The external surface of the vaulted roof has a continuous convex configuration with a slowly varying radius of curvature and no change of signal such that over pressures and shockwaves striking the external surface of the vaulted roof apply compressive pressures to the vaulted roof and are deflected by the surface. Optionally, there may be one or more basement levels below the flat floor which are enclosed by inner and outer walls having a ring configuration which are joined to the inner and outer edges of the vaulted roof. In another option the flat floor may be replaced by an arch with its concavity facing upwards joined to the inner and outer edges of the vaulted roof.

  • Patent number: 5046258
    Abstract: A wrapping machine, particularly for wrapping cigarette packets in wrapper film, includes a series of endless band conveyors (148, 152, 156, 166, 170) carrying pushers (150, 154, 158, 172) for moving successive packets (191) along a straight wrapping line. One of the pushers (158) is heated to seal a wrapper seam. Opposed heated band conveyors (166) simultaneously seal end folds of the wrapper. Packets are gripped between opposed conveyors (145, 148) immediately after intercepting a wrapper (100). Partially-wrapped packets are arranged to slide relative to surfaces (149, 153, 157, 180) to attain wrap tightness. Successive conveyors (e.g. 156, 170) are independently driven to allow phasing of the conveyors to vary the position at which packets are transferred between them.

  • Patent number: 4882760
    Abstract: A system for reproducing sound, particularly musical sound, giving enhanced pleasure to the listener. The system utilizes a pair of low frequency range speakers, a plurality of high frequency range speakers and may employ one or more mid frequency range speakers, all of which speakers are of conventional construction. These speakers are, however, disposed in a novel mechanical arrangement and electrically interconnected in a manner to emanate sound in essentially a non-directional manner. The listener thus perceives the sound to be emanating from the diemensional space surrounding the system, rather than from a single point or plane, and experiences the sound much as if he or she were in the same enclosure with live performers, rather than listening to a recording.
